Mauro Locatelli:> Is there a way to distinguish among incoming calls in asterisk.
Yes.

OK.

Yes.

First off, make sure the line in zapata.conf
"immediate=no"
exists.
Then in your extensions.conf context for your zap inbound calls:
-------8<--------
exten => 1234JOHN,1,Dial(SIP/John)
exten => 1234HENRY,1,Dial(SIP/Henry)
-------8<--------
You may have to play about to find the correct number of digits for the
extension (mine here in the UK needs 6).
Have fun.
Nick.
